"Security forces have since cordoned off the blast site and are now searching for the attackers," he said.

The bombing, al-Orfi added, had resulted in "significant material losses".

Benghazi’s Al-Jalaa Hospital, for its part, said it was treating the six people injured by the blast.

Last Friday, one person was killed and another ten injured -- including a former interior minister and his son -- by a car-bomb that went off near central Benghazi’s Abu Hurayra Mosque.

Another four people were killed in Benghazi last November, including three children, when a car-bomb went off near the Al-Jalaa Hospital.

At the time, Fathi al-Majbari, vice-president of Libya’s Tripoli-based UN-backed unity government, blamed the deadly attack on "terrorist organizations" in reference to Daesh and the Ansar al-Sharia group.

Earlier the same month, five other civilians were hurt by a similar car-bomb attack near a park in Benghazi.
